Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5-147383-7 are identified based on alignment of critical electrical and mechanical parameters. The following parameters determine substitution eligibility:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 70
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Termination: Solder
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Material Flammability Rating: UL94 V-0

The substitute parts listed (Samtec TFM-135-32-L-D and TFM-135-32-S-D-A) satisfy all primary matching criteria. Variations in contact length, insulation height, contact shape, current rating, and operating temperature range represent design differences within the same functional category and do not preclude substitution when these parameters are acceptable for the target application.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec substitute parts (TFM-135-32-L-D and TFM-135-32-S-D-A) maintain Active product status and comply with current regulatory requirements. The TFM-135-32-S-D-A variant includes a Board Guide feature and matches the contact finish thickness specification of the original part at 30.0µin (0.76µm), whereas the TFM-135-32-L-D provides a thinner gold finish at 15.0µin (0.38µm).

Both Samtec parts are ROHS3 Compliant and REACH Unaffected, representing current compliance standards. The extended operating temperature range (-55°C ~ 125°C) of the Samtec parts exceeds the original specification (-65°C ~ 105°C), providing broader thermal capability. The higher current rating (2.9A per Contact) and specified voltage rating (275VAC) of the Samtec parts indicate enhanced electrical performance characteristics.

Selection between the two Samtec alternatives depends on specific application requirements regarding contact finish thickness and the presence of board guide features. Both parts are suitable for direct substitution in applications where the original part specifications are met or exceeded.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 5-147383-7?

A: The critical parameters are connector type (Header), contact type (Male Pin), position count (70), row configuration (2 rows), mating pitch (0.050"/1.27mm), row spacing (0.050"/1.27mm), mounting type (Surface Mount), shrouding (Shrouded - 4 Wall), fastening type (Push-Pull), termination method (Solder), insulation material (LCP), contact material (Phosphor Bronze), and contact finishes (Gold mating, Tin post). All substitute parts must match these specifications.

Q: Can the Samtec TFM-135-32-L-D and TFM-135-32-S-D-A be used interchangeably with the TE Connectivity 5-147383-7?

A: Both Samtec parts satisfy the critical electrical and mechanical parameters required for substitution. The primary difference between them is the contact finish thickness (15.0µin for TFM-135-32-L-D versus 30.0µin for TFM-135-32-S-D-A) and the presence of a Board Guide feature in the TFM-135-32-S-D-A. Selection depends on application-specific requirements for these features.

Q: What packaging differences exist between the main part and substitute parts?

A: The TE Connectivity 5-147383-7 is supplied in Tape & Reel (TR) packaging, while both Samtec substitute parts are supplied in Tube packaging. This difference affects handling and storage procedures but does not impact electrical or mechanical compatibility.

Q: How do the operating temperature ranges compare?

A: The TE Connectivity 5-147383-7 operates from -65°C to 105°C. Both Samtec substitute parts operate from -55°C to 125°C, providing an extended upper temperature limit of 20°C and a reduced lower temperature limit of 10°C. Applications requiring operation below -55°C must retain the original TE Connectivity part.

Q: What is the difference in current rating between the main part and substitutes?

A: The TE Connectivity 5-147383-7 is rated at 0.5A per contact, while both Samtec substitutes are rated at 2.9A per contact. This represents a significant increase in current-carrying capacity. Applications with current requirements exceeding 0.5A per contact benefit from the higher rating of the Samtec parts.

Q: Are there compliance differences between the parts?

A: The TE Connectivity part is RoHS Compliant, while the Samtec parts are ROHS3 Compliant, representing a more recent compliance standard. Both parts carry EAR99 ECCN classification and share the same HTSUS code (8536.69.4040). The Samtec parts are REACH Unaffected, whereas the TE Connectivity part lists REACH status as Vendor Undefined.

Q: What is the significance of the contact shape difference (Circular versus Square)?

A: The TE Connectivity 5-147383-7 features circular contacts, while both Samtec substitutes feature square contacts. This geometric difference does not affect mating compatibility with standard receptacles designed for 0.050" (1.27mm) pitch connectors, as both contact geometries are compatible with standard contact cavities.

Q: How do the contact length specifications affect substitution?

A: The TE Connectivity part has a mating contact length of 0.120" (3.05mm), while both Samtec parts have 0.139" (3.53mm). The longer Samtec contacts provide increased mating depth and may affect overall mated stacking height. Applications with space constraints should verify compatibility with the increased contact length.
